Representative eye fundus after dissection of ocular tissue in control (a) and COVID-19 patients (b–d). a Ocular tissue of a control patient with a slight hyperpigmented area in the temporal portion (inset, green arrowhead). b–c Dissection of samples from COVID-19 patients showing drusen deposits in the limits of the macula (b, white square, inset), hyperpigmented areas (b, c, green arrowheads) and a small flame-shaped hemorrhage superior to the optic nerve (c, blue arrow, inset). Mild peripapillary atrophy (b) and ischemia (c) can be also observed. d Eye fundus of a COVID-19 patient without remarkable alterations. Fovea (yellow arrow, inset) and optic nerve at higher magnification (inset). The choroid vessels (seen as white lines throughout the fundus) branch from the periphery to the fovea in all of them.
